Yes; for now. Hopefully at some point there will be a IPv6-aware &=20 native replacement for cvsupd, and if so, I hope to be the first one=20 running it. (and no I am not interested in 6tunnel'ing; this isn't 2003 anymore) > Given that the servers are all using the cvsup > program, it wouldn't surprise me if they can't handle connections > from IPv6 hosts. But if that's the case, then why are there AAAA > records for the cvsup*.freebsd.org hostnames? Because the mirror *.freebsd.org hostnames are in fact CNAME's; in=20 cvsup4's case it's pointed to freebsd.isc.org, which has the A & AAAA=20 records, and we do offer IPv6 for www5 and ftp4. I don't really see it as a problem at the moment since IPv6 connections=20 via csup to cvsup4 are immediately refused and it retries on the IPv4=20 address which will hopefully just work. (I assume your friends are dual=20 stack and are not IPv6 only?) > (apologies if this was a dumb question, but I haven't done much with > IPv6) No worries. Hope this helps clear this up for you.
